Reports negated boolean expressions that can be simplified.
<p>The quick-fix simplifies the boolean expression.</p>
<p><b>Example:</b></p>
<pre><code>
    fun test(n: Int) {
        !(0 == 1)
    }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
    fun test(n: Int) {
        0 != 1
    }
</code></pre>
<p>Please note that this action may change code semantics if IEEE-754 NaN values are involved:</p>
<pre><code>
    fun main() {
        println(!(Double.NaN &gt;= 0)) // true
    }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
    fun main() {
        println(Double.NaN &lt; 0) // false
    }
</code></pre>
